COMBINED HEMMER AND LACE-GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 332,700, dated December22, 1885.

Application filed July 7, 1885. SerialNo. 170,884. (Model) To 01. whomit may concern:

Be it known that I, WILLIAM R. CLARK, a citizen of the United States,residing at De troit, in the county of Vayne and State of Michigan, haveinvented certain new'and useful Improvements in Combined Hemmer andLace-Guide for Sewing-Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

The object of my invention is to provide a simple and convenientattachment for sewingmachines, for turning a. hem on the edge of a pieceof fabric as the latter passes to the sewing mechanism, andsimultaneously guiding a strip of lace or other material to the needle.

To this end my device consists ot'a supporting-plate, preferablyprovided with a presserfoot, and thus adapted for attachment to theresser-bar of a sewing-machine, said plate having on its upper side ahemmer of any ordinary or suitable construction. In front of the hemmeris preferably placed a frictionspring, between the free end of which andan inclined rib or projection beneath it the fabric to be hemmedpasses,said inclined projection, against which the fabric is gentlypressed by said spring, having a tendency to deflect the fabric towardthe hemmer in a well-known manner, and thus keep the edge of the goodsin the hemmer. The supporting-plate is provided on its under side withaguiding-passage for a strip of lace or other material, said passagebeing mainly on the inner side or to the right of the hemmer, the outeredge of said passage being directly beneath orin line with the hemmer,sothat the edge ofthe strip guided thereby will be presented to the needlebeneath the hem, and will thus be attached to the fabric by the lineofstitches by which the turned hem is secured. The strip-guidingpassageis preferably made adjustable to adapt it for use with strips ofdifferent widths.

In the drawings, Figure l is a plan view of my combined hemmer andguide. Fig. 2 is a bottom view, Fig. 3 a side view, and Fig. 4 a frontview, of the same. Fig. 5 is a perspective bottom view of my device withthe guide-piece detached, and Fig. 6 is a perspective view of saidguide-piece.

A indicates the main or supporting plate of my device, and B is apresser-foot, by which said plate may be removably fastened to thesewing-machine presserbar. Secured to the plate A in front of theneedle-opening b ofthe presser-foot is an ordinary twisted hemmer,0,said hemmer being preferably formed integral with its attaching-plate c,which is bent over to form an outwardly-extending springarm, D, andbeneath the outer or free end of the latter is an inclined rib orprojectiomc, herein shown as being struck up from the plate a, theinclination of said rib being indicated by the dotted lines in Fig. l.The supporting-plate A has on its under side an inclosed guidingpassage,E, for the strip of lace or other material which is to be attached tothe edge of the fabric by the stitches which secure the hem, saidguiding-passage being forward of the rear end of the hcmmer, and belowand mainly on the inner or right-handside of the latter, Fig. 1, withits outer edge directly beneath or in line with said hemmer. Theguiding-passage, as herein shown, is formed by a downwardly and inwardlyturned lip,a, on the plate A, and an adjustable hollow guide-piece, F,formed ofthin metal,and having spring-armsf f, passing through slots ain a rib, a, on the under side of the plate A. The guidepieceF may beadjusted toward or from the lip a, to vary the width of theguiding-passage E, the spring-armsff havingsuflicientfriction in theslots at of the rib a to hold saidguide-piece in any position to whichit may be adjusted. The

' bottom of the presser--foot B is preferably recessed slightly at b onits inner side, beneath which the hem and the secured strip passes, soas to compensate for the increased thickness of the work at this side,and thus insurethe accurate working of the feed.

In the use of my device the fabric to be hemmed passes beneath thespringarm or friction-spring D, the latter pressing the fabric gentlyagainst the inclined rib c, which has a tendency to deflect thefabrictoward the hemmer O, which latter turns in the edge to form a hemin the usual manner. The strip oflace or other material to be attachedto the edge of the fabric simultaneously with the sewing of the hempasses through the guiding-passage E, and as the inner edge of thelatter is in line with the hemmer, the accurate presentation I 10 therear end thereof, an inclosed strip-guiding passage,which is mainlyinside or to the right of said hemmer, but having its outer edge in linewith the latter, substantially as set forth.

2. In asewing-machine attachment, the com- I5 bination, with asupporting-plate having a strip-guiding passage on its under side, of ahemmer supported above said plate, a frictionspring in front of saidhemmer, and an inclined rib or projection beneath the outer end 20 ofsaid friction-spring, substantially as set forth.

3. The combination,with the hemmer, of the supporting-plate having thelip'a and slotted rib a, of the adjustable guide-piece F, said lip andguide-piece serving to form an adjustable or variable strip-guidingpassage, substantially as set forth.

4.. In asewing-inachine'attaohment,the combination,with a hemmer,ofasupporting-plate therefor, having on its under side, below the hemmerand forward of the rear end thereof, an inclosed strip-guiding passage,mainly inside or to the right of said hemmer, and a presser-foot havinga recess, as b, 0n the inner side of its lower or bearing surface,substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM R. CLARK.
